Abstract: ABSTRACT  OF  THE  DISCLOSURE         The instant invention relates to a method for removing dissolved compounds from solution by decomposing them and removing the decomposition products continuously and simultaneously by at least two different mechanisms.  The decomposition is an equilibrium reaction, thus simultaneous removal from the solution of two or more products of decomposition results in efficient and complete removal.  Preferably, the dissolved compound is the hydrolyzable salt of a weak acid and a weak base in an aqueous solution.  The simultaneous removal processes for the hydrolysis products include stripping, distillation, extraction, adsorption, and liquid membrane separations.  Preferably, more than one process is utilized to remove the separate decomposition products; that is, the method utilized herein relates to a process wherein one decomposition product is removed by adsorption on or reaction with a solid sorbent, while the other decomposition product is simultaneously stripped with steam. The removal processes are further selected so as to leave behind a solution which is substantially free from the starting compound and any of its undesirable decomposition products.

Abstract: Abstract of the Disclosure A disposable multi-layer diaper includes at one surface a porous fibrous facing layer to be brought into contact with the infant's skin, and includes at the other surface, a water-impervious backing sheet, with an absorb-ent batt being interposed between the facing layer and backing sheet.  The facing layer is comprised of two half-thickness portions, the outer half-thickness portion to be positioned adjacent the infant's skin, being readily separable from the inner half-thickness portion, and from the remainder of the diaper, so that the outer half-thick-ness portion and any fecal matter thereon can be flushed down a standard toilet separate and apart from the remainder of the diaper including the non-degradable water-impervious backing sheet.  The outer half-thickness portion is charac-terized by a given overall concentration of long and short fibers, the outer face having a concentration of long fibers in excess of the given overall concentration of long fibers in the half-thickness portion, with the long fibers decreasing in concentration closer to the inner face of the outer half-thickness portion.  In the preferred embodiment, the inner half-thickness portion of the facing layer is of the same fiber concentration structure as the first half-thickness portion and through-bonded thereto with the short fiber enriched faces in juxtaposition.  The concentration of short fibers at the interior of the facing layer provides a layer of weakness therein which permits the facing layer to be manually delaminated along the short fiber plane for the disposal of fecal matter.

Abstract: DISK GENERATOR                 ABSTRACT OF THE DISCLOSURE     A one level, replication generator for cylindrical, single wall magnetic domains or "bubble" domains comprises a disk and a conductor that connects the disk to the elements of an adjacent bubble domain propagation path.  The disk and conductor can be formed from permalloy while the propagation path, which typically comprises chevron-shaped elements, can also be formed from permalloy.  The conductor and disk can be formed to the same level.  That is, they can be formed using a one-mask fabrication process, thus precluding the problems of alignment where several mask sequences are used.  In operation, a bubble domain seed circulates about the disk under the influence of a cyclically varying, in-plane magnetic drive field.  When the drive field is at a suitable orientation, a current pulse is applied to the conductor to cause the bubble domain to strip out to the propagation track.  Upon application of a pulse of reversed polarity, the stretched domain is cut, allowing the severed domain to propagate along the track and the seed domain to continue around the disk.

Abstract: GATING CIRCUIT FOR A VIDEO DRIVER   INCLUDING A CLAMPING CIRCUIT           Abstract of the Disclosure An amplifier for combining color difference signals with luminance signals and driving a color image reproducing device includes first and second transistors of opposite conductivity type.  Color difference signals are capacitively coupled to the base of the first transistor. The base-emitter junction of the first transistor is      direct current coupled in feedback relation across the collector-base junction of a third transistor of like conductivity type.  The emitter of the third transistor is coupled to a gating circuit which couples a reference voltage to the emitter of the third transistor to cause the third transis-tor to conduct during each horizontal retrace interval.  As a result, the emitter of the first transistor is clamped substantially to the reference voltage to thereby determine the operating point of the first transistor.  The gating circuit also selectively couples a signal to the emitter of the first transistor to render the image reproducer cut-off during the horizontal trace portion of the vertical retrace interval so that disconcerting horizontal scan lines are not visible during vertical retrace.  The gating circuit is arranged so that the signal to cut off the image reproducing device during vertical retrace is disconnected from the emitter of the first transistor during the horizontal re-trace intervals so as not to interfere with the clamping operation of the first and third transistors.

Abstract: ABSTRACT           A steering and transmission arrangement for an off-road all-terrain vehicle provides for the drive ratios to each of the vehicle wheels to be geared up and down in unison so that each wheel receives a torque which is an average of the torque requirements of all the wheels.          Steering is effected by varying the drive ratios to the left-hand and right-hand wheels differentially so that the wheels on one side are speeded up and the wheels on the other side are slowed down.  The wheels axe supported independently on longitudinally-extending legs pivotally connected on the vehicle body.  Problems of stress on the drive train as the wheel legs rock up and down on rough terrain are avoided through a speed-reducing coupling at the pivotal leg connection and a torsional energy-storing drive shaft between the coupling and the wheel which absorbs small torques induced by the rocking of the legs and by rotational advancements and retardations of the wheels as they ride over local bumps in the terrain.
